Preparation of smart paper part I—formation of nylon microcapsules on paper surface using interfacial polymerization

In this study, nylon microcapsules were prepared on a paper surface using an interfacial polymerization technique for the preparation of smart paper. Filter paper impregnated with ethylenediamine solution and NaOH solution was left in a beaker containing cyclohexane or chloroform. Subsequently, the organic solvent terephthaloyl chloride was added to the beaker and interfacial polymerization occurred on the paper surface. When cyclohexane was used as the organic solvent, formation of nylon microcapsules on the paper surface was confirmed. Fixation of nylon microcapsules on the paper surface was successfully performed using interfacial polymerization. On the other hand, it was not possible to form nylon microcapsules on the paper surface when interfacial polymerization with chloroform was carried out. These results are due to differences in the spreading coefficient of the organic solvent on the ethylenediamine solution adsorbed on the paper surface.
